In the latest version of IronRuby (0.3), the ability to use Generic .Net classes was added. I couldn’t find anywhere how to do that so I dug it out of the code and now I’ll share it with you!
Example #1 - List
This is how to define an Int32 list, add two numbers to it and print them:
|
list = System::Collections::Generic::List[System::Int32].new
list.add 4
list.add 12
list.each { |x| puts x }
|
Of course we can also use Ruby type like Numeric, String, etc.
Example #2 – Dictionary
This is how to declare a number-string dictionary, add values to it and print them:
|
dict = System::Collections::Generic::Dictionary[Fixnum, String].new
dict.add 1, "Hey"
dict.add 15, "There"
dict.each { |x| puts "#{x.key} - #{x.value}" }
|
All the best,
Shay.
